5 Claims.

My invention relates to household articles and more particularly to adoor stopper.

The object of my invention is to provide a door stopper consisting oi arelatively stationary base part supporting a spring biased top partadapted to engage the under edge of a door to secure it in adjusted openposition.

Other objects of my invention not specifically mentioned may appear inthe following specication describing my invention with reference to theaccompanying drawing illustrating a preferred embodiment of myinvention. It is however, to be understood, that the invention is not tobe limited or restricted to the exact construction and combination ofparts described in the specification and shown in the drawing, but thatsuch changes and modifications may be made, which fall within the scopeof the claims appended thereto.

In the several figures of the drawings similar parts are designated bysimilar reference chai'- acters and Figure l is a View in side elevationof a door stopper constructed in accordance with the present invention,showing the same in use.

Figure 2 is a top plan view of the same.

Figure 3 is a vertical longitudinal section through the door stopper.

The door stopper forming the subject matter of my invention comprises arelatively stationary base B preferably made in one integral piece andhaving a base plate lll, from which a substantially cylindrical hollowbody lI extends upwardly. The body is arranged adjacent one end of thebase plate and symmetrically about the longitudinal center line of saidplate, In the top of the body il a central opening i2 is providedleaving an inwardly extending circumferential flange I3 for a purpose tobe described later. The circumferential portion of the base plate Illforms a downwardly open hollow lll.. A rubber foot pad l5 has the samecontour as the base plate l il, and the circumferential portion of thefoot pad is provided with an upwardly extending reinforcement l adaptedto be pressed into the circumferential hollow Ill of the base plate Iii,so that said base pla-te rests on the foot pad l5 and is prevented iromaccidentally sliding from said pad.

Since the body l I is arranged adjacent one end of the base plate, theother end of this plate extends a comparatively long distance beyond thebody H. In the wall of the cylindrical body an axial groove or key wayil is provided for a purpose to be described later.

A spring retainer R has a substantially cylin 55 drical cup-like bodyI8, on the upper edge of which an outwardly extending circumferentialvilange I9 is formed. The cylindrical cup-like body of the springretainer lits slidably into the opening I2 in the top of the base B andthe flange i9 on the spring retainer rests on the iiange I3 of the base.

A top member T has a substantially cylindrical body 2U iitting slidablyover the cylindrical base body Il. On the lower edge portion of the topbody 20 a radially extending comparatively broad stop lever 2l isformed, the lower edge of which is arranged at the same level with loweredge of the top body, and the upper surface of which is provided withupwardly extending short teeth 22. A portion of the top body 2t locatedadjacent the lower edge thereof is pressed inwardly to form a key 23fitting slidably into' the key way Il in the base body I I and holds thestopper lever 2| in correct alignment with the large portion of the baseplate lll. A helical spring 24 is set into the retainer R and engagesthe top member T urging it upwardly on the base body II.

When the above described door stopper is to be used to hold a door 25 ina desired open position, the door stopper is put in the desired place,and the top member is forced downwardly compressing the spring 24. Thedoor 25 is opened so that it extends over the toothed stop lever 2l andthe top member is released. The spring urges the top member upwardly, sothat the toothed stop lever engages the lower edge of the door 25securing it in the desired position. The rubber foot pad I5 prevents anyaccidental sliding movement of the door stopper on the door.

On the upper end of the key way I7, a shoulder 26 is formed to preventthe top member T from being pushed entirely oir the base body I I by thehelical spring 2li, when the door stopper is not in use.

I claim:

' 1. A door stop, comprising a flat base adapted to be inserted beneatha door, a cylinder disposed uprightly upon the base, the cylinder havingan opening in its top end, a cylindrical top having an open lower end inwhich the top of the rst cylinder is slidably received, the top end ofsaid cylindrical top being closed, a dat stop lever integral with thecylindrical top and extending horizontally therefrom in spaced parallelrelation with and above said base, a cup suspended in the said openingin the top of the rst cylinder, and a spring positioned in and supportedby said cup and housed within and pressing upwardly against the closedtop of said cylindrical body.

2. A door stop of the character stated in claim 1, with coacting meansbetween the said cylinders permitting reciprocal movement of thecylindrical top upon the first cylinder but maintaining the cylindersagainst relative turning movement.

3. A door stop of the character stated in claim 1, wherein the firstmentioned cylinder has a longitudinally extending key way groove pressedin the wall thereof and said cylindrical top has an in pressed keyslidably engaging in said groove.

4. A door stop of the character stated in claim 1, wherein said cup isprovided with a lateral flange engaging and resting upon the upper endof the rst mentioned cylinder to maintain the cup in the said. suspendedposition in the rst mentioned cylinder.

5. A door stop of the character stated in claim 1, wherein said baseincludes a relatively long metal 4 plate with which the rst mentionedcylinder is formed as an integral part, the said metal plate having adownward depression in which the said flat stop lever positions when thecylindrical top is moved downwardly to the limit of its movement, andsaid base further comprising a resilient friction pad covering theentire undersurface of said metal plate.
